WiFi radio spontaneously became extremely weak - Galaxy S III Q&A, (US Carriers)

I have the Sprint SGS III, and have been happy with its network and wifi performance up to this point. However, randomly, my phone started to not connect to WiFi. I was concerned, so I restarted it, hoping that would fix it. It did not. Then, I tested to see if it would connect if it was right next to the router, and voila, it did. But as soon as it was more than ten feet or so away, it would lose signal, and the strength deteriorated very rapidly from moving away from the router. I also tried booting into CyanogenMod from recovery, but the issue was still there. Has anyone else experienced this?
Is there a way to reset the wifi firmware, or something to that effect? Or should I assume that it's a hardware issue?

[Q] Wifi Roaming

Is there any mod or fix or even any news at all on how to get wifi roaming working on the s3?
For anyone who doesn't know - if you have multiple routers/access points then when they overlap they do not transition correctly. You have to disconnect and reconnect to get onto the most appropriate router.
I have a router upstairs in the back of the house and downstairs at the front so I can get coverage in the garden etc... if I'm downstairs and move upstairs it'll hang onto the signal from downstairs even if low when the signal from the other router is much better. you have to disconnect and reconnect to get a better signal.
It's the only really annoying thing about this phone!
Edit spoke to samsung uk technical and they said they are aware and it should be fixed in the next firmware but tbh I think they were just bull****ing me.

I got the same problem. I got my S3 some weeks ago. All worked fine (or I did not realized the problem). But since the official Jelly Bean update I am also stuck in this problem at work. In our office there are several access points and as along as I stay connected to one of them all is fine. When I leave my desk and fetch a coffee at the meeting point, the S3 should switch to another AP.....So, staying at the meeting point with the coffee but no WiFi... After switching the WiFi off and on, it works again. Coming back to my desktop, I have to switch WiFi off and on again....really anoying bug....
Any solutions? Or maybe Custom ROMS?
Thanks

[Q] Wifi Problem after CM11

Hi All, I've searched around and can't find threads that are exactly what I'm experience, so I'm hoping this is something the community can help with. I've been experiencing this problem since flashing CM11 a few months ago. My wifi has no problem searching and connecting, but intermittently while on wifi, I'll notice that I'll only send data and not receive it. Waiting 15-30 seconds will usually have it come back, or disabling/enabling will also fix it, but it's never consistent. I notice when the phone is plugged in, the wifi connection stays pretty good.
Just to clarify, I am not losing the wifi signal and the phone stays connected to the network. This happens in all kinds of wifi (whether home or work). Any help would be appreciated!

[Q] Weak wifi reception

Hey guys,
So I've been having some problems with my wifi reception on my Galaxy S4. I'm not entirely sure as to what the problem is, but hopefully you guys can help me.
Unless I am very close to my router (~10 ft.), my wifi reception is marginal. However, sometimes, when I am far away from my router, and I put pressure on the back of my phone near the power button, the wifi signal instantly boosts up again. It is for this reason that I originally thought that the problem was with the wifi antenna. I changed the back housing which contains the wifi antenna, but to no avail. I have done everything you would find online such as keeping wifi on when sleeping, etc.
Please help me out. I really need my wifi.
Thanks.

Wifi and Bluetooth randomly dropping out

So I've noticed that randomly throughout the day my phone will randomly disconnect from Wifi and Bluetooth. It always drops both at the same time then reconnects.
Has anyone else had this problem?
For me the Mobile Connection Drops every few seconds.....No Network...4G TLE with 5 Bars.......No Network...4G TLE with 5 Bars.....No Network...4G TLE with 5 Bars.....No Network...4G TLE with 5 Bars...
Got my My LG G5 from T-Mobile... After 3 days the phone has been overheating, and every 10 seconds it drops Mobile Connection...I went through a plethora of tests with T-Mobile Support and they determined that I need a replacement device...so waiting for the replacement...One other thing, I notice this happened after calling T-Mobile to Unlock the device...So not sure if there is any correlation between my issue and T-Mobiles Unlock App, T-Mobile said the two were not related.
WiFi is unstable for me, too. Disconnects randomly every hour or so. I mostly notice it when casting to my Chromecast. I have to reconnect to the app in order to regain control. I've tried multiple routers, and the problem is reproducible with both. Bluetooth hiccups, too, but never fully disconnects. I haven't noticed that the WiFi and Bluetooth disconnects coincide. Mine is AT&T branded.
I've got a similar issue, only the wifi is fine most of the time, but Bluetooth skips every few minutes and has completely dropped twice. I'm exchanging my device tomorrow to see if that fixes it. I also got a crap battery as well. Kinda disappointed with this $700 purchase.

Me too, i disappointed
Okay so, I've only managed to reproduce it on 5GHz networks. It doesn't seem to drop out on the 2.4GHz band. Bluetooth doesn't drop out either.
Scrap that, just happened again at work on a 2.4GHz connection. Hopefully it's just a software bug that will be fixed in a later patch.
I have 5Ghz wi-fi at home and it's been rock solid. Have also had no issues with bluetooth. Hope you get it figured out.
Both bands Wi-Fi & BT rock solid for me too. The BT in particular seems much stronger than my 6P which had occasional drop outs even at close range.

I notice that it reports "Avoiding poor connection" in the WiFi menu when it's disconnected. I'm sitting in the room with the router, so maybe the "poor connection" detection is too aggressive.
Mine just starting dropping WiFi while the screen is off, I check the settings and everything is setup right it just started to happen today. I would F/R the phone and see if that helps
I exchanged mine for a new one, and the WiFi connection remains inconsistent.

Mine also does this and seems to be getting worse also vibrations have also stopped all together
I can't even get through 1-2 songs on bluetooth before it disconnects and plays through my phone speakers... it has zero issues connecting in the first place and sounds fine, but then just drops.
I do have pretty unreliable wifi at home so I'm playing some music with wifi switched off to see if it could somehow be related to wifi dropping, but these songs I'm playing are cached to my phone from Play Music so that'd seem weird to me..
Also wondering if hardware and distance has an issue with it. I had it 2-3 yards away from my bluetooth shower speaker when it disconnected. I'm playing it right next to it now and so far into song 2 with no issues. I've never had this issue with my G4, which is a bummer, because that phone was a piece of junk that my G5, otherwise, outclasses in every possible way.
To update, the Bluetooth issues absolutely seem to be linked to wifi drops, at least from my testing. Even playing local media, I noticed both dropped at the same time, but I played through 5 songs with my wifi toggled off and not a single problem.
Those of you with issues in the car, is your wifi toggled off completely? I'm wondering if it's affected by having wifi on, or just by a random wifi drop.
I've had wifi issues with every Android phone I've owned since IPv6 became normal in home routers. I blame Google for refusing to use DHCPv6, the most widely used dynamic network addressing protocol, instead using some weirdass protocol called RDNSS which NOBODY uses. I've found the best fix is to ensure your router is set to stateless autoconfiguration for IPv6, but it doesn't fix it completely. Those who have a router that can shut v6 off, try it out. Xfinity doesn't let you.
I will say my g4 behaved the exact same way on wifi, but I don't remember Bluetooth having issues. I don't use it much, though, since I have an AUX in my car and Chromecast music.
Having the same issue as well. Fought with sprint for weeks and went through a few replacements in that time... Got the G5 as a free upgrade and it's doing the same thing. Done with LG devices...
Yes, and I just made a thread about it. Oops. Anyone try resetting phone? I'm about to but that's a pain having to bring it all back and make sure I back everything up.

That is not promising as I've had this issue since day one hoping an update would solve it to no avail trying to avoid getting a replacement.
My last phone did the exact same thing. For 2 years. Also constantly closing apps I was using, freezing, and my keyboard would disappear frequently. It did it from Day 1. It was a nightmare.
Finally got a new phone (and moved up to Marshmallow,) and the drops have started happening after less than 1 week. They really need to find out what's causing this!

Wifi disconnecting?

Hi,
Long time member, but rarely post.
Xperia 1 is my 4th Sony phone and I'm having some problems with the WiFi disconnecting.
Since I've had the phone my WiFi keeps disconnecting. The phone can still see the network on the WiFi settings page, but I have to reconnect. Anyone having the same problem?
On previous Xperia there was an option to turn off the WiFi when the screen switched off, which I always unchecked. But I can't see this option (or anything similar) on the Xperia 1.
Love the phone otherwise, emulators, PS4 remote play and everything I want it to do it does seamlessly.
Thanks in advance.
maybe a different issue but I have a problem Wifi gets disconnected whenever the upper part of device is covered with my hands. This happens often when I hold the device horizontally.
No issues with my Wifi. Everything has been solid so far. I use Googlw Wifi mesh APs.
Maybe you have auto network switch on?
Also when I turn my phone horizontal and cover, I do loose 1 si gle strength.
Same here .. I sent back Xperia 2 week ago and they sent me another One.. now I've issues with Wi-Fi, camera focus sometimes go Crazy and also 2x camera doesn't work properly, in the camera preview when you use 2x Lens It looks blury..

Nothing, it's been like this since I got the phone.
If you're meaning what did I do to fix it, nothing I've done has fixed it.

Unfortunately, my phone already slipped out of my pocket and now has a small crack on the back. Highly doubt I'll be able to return it and get a swap if its damaged.
The WiFi problem only seems to happen at home. No problem with my old XZ Premium or the wife's phone. I've reset the router, forgot and reconnected to the home network but the issue still persists. Not a huge issue really, just slightly annoying.

Unfortunately for me, it is, I often leave airplane mode and if it disconnects I lose notifications, looks like it doesn't reconnect automatically, I have to do it
Got to say the Xperia 1 wifi reception seems weaker than my previous phone OnePlus 5. But my wifi never disconnect itself when the signal is strong enough. Only happens when the signal is very weak.
Have you tried messing around the wifi preferences setting?

Yes, after 2 defective units, I ask for a refund, I get one plus, sad because I like a lot Sony apps like album and camera.. but then again sucks there's no hdr option in the camera
I had a spell where this was happening as well, I reset the wifi router and "forget" the network in the phone and it has been much better since. Like others have said here, the wifi strength is not as good as on all my previous recent Sony phones for some reason.
I have this issue as well. Coming from Xperia XZ, I can confirm WiFi seems to be not as resilient on the Xperia 1. That said, at home I have a Google WiFi mesh network and is rock solid, its only at work that I have the disconnect issues.
At work I can see my phone will connect to 2.4Ghz with good/excellent strength, then it tries to hop to 5Ghz where it see 0-1 bars and milliseconds later it's a coin flip between disconnecting WiFi or failing back to 2.4ghz. This is the endless loop that I'm in.
So to me the issue is the phone is overestimating the signal strength of the 5Ghz connection, and getting burned each time it attempts to use it. I don't know enough about WiFi protocol but it seems plausible that the strength could be different once actually connected. I'm not sure the answer to this, but I do believe this is more or less the root cause.
HELLO wifi problems
Hi all,
I have a similar problem
I usually keep my data switched off ( at home) and WiFi off when not going online
so throughout the day I switch WiFi on and off like 20 times, 8/10 it connects but for some reason it hangs sometimes.
Quite annoying, I have auto connect on
This never happens on my XA1 ultra
Any solutions?
PS. Software repair, firmware update, factory reset, WiFi reset all done, but intermittent wifi connection persists
I am mostly online in two networks one is a mesh the other a single router.
I always have troubles with the mesh but is not exclusively to my xperia, there are troubles with iPhones and Samsung has connection issues too I think it's a general problem with mesh networks.
I didn't find any solution to this.
